Sonifex adds IP to silence detector

Published:

Amongst a host of new products, Sonifex has released the upgrade to its RB-SD1 silence detector. Named RB-SD1IP, the new silence detection unit is a 1U rack mount device used to monitor an unattended stereo studio feed. In the event of the signal going ‘quiet’, after a given period the unit will switch to an alternative stereo audio signal. This signal could be a recorded message, a feed from a flashcard player, audio from a connected USB flash drive or an alternative recorded programme.

The upgraded unit features the same functionality as the RB-SD1, but with extra features such as Ethernet connectivity to control the unit with a browser-based GUI. The network capabilities allow the user to more finely control silence level (-60dBu to 0dBu in 3dBu steps) and silence duration (1s to 10 minutes). Users can also remotely lock/unlock the front panel controls on the unit and opt to use either the hardware configured settings or web based settings. In addition to the front panel LEDs the GUI home page offers a real time view of signal levels and alarm statuses.

Using the new browser GUI, left and right channels can be treated independently and remote relay triggers can be configured as one of many events including the new GPIO pins. Users can also choose to lock/unlock the use of the remote pins to control the unit and firmware updates can also be performed using the web GUI. SNMP V1 is implemented so that the unit can be controlled by existing network management systems. The addition of six extra GPIO pins to the rear panel allows the use of the RB-SD1IP network interface to generate SNMP Traps on behalf of non-networked hardware. The RB-SD1IP has been fitted with a USB interface on the front panel which can be used to upgrade the firmware on the unit from a USB flash drive or play out stored audio in the event that both main and auxiliary signals fall silent.

Away from silence monitoring, the RB-DDA6A3 digital distribution amplifier is used for distributing AES3id digital audio, repeating both the audio data and the status information of the input whilst re-normalising to standard digital audio levels. It has a single BNC AES3id audio input which is distributed to six BNC AES3id audio outputs.

Also new from Sonifex are two telephone hybrid units. The two new units are the DHY-04 single automatic digital TBU with AES/EBU and analogue I/O, Ethernet, and the DHY-04G single automatic digital GSM hybrid, with AES/EBU and analogue I/O, Ethernet.

The DHY-04 telephone hybrid has front-panel speed-dial buttons and auto-sensing AES/EBU or analogue XLR inputs and outputs. It has an Ethernet port for remote configuration and remote control of the unit with SNMP. It also has DTMF dial up recognition for reporter remote access and hybrid control over a standard POTS line. The DHY-04G is a digital GSM hybrid which has all features of the DHY-04 but uses a 2G cellular connection.
